Rated at 208 V AC, 60 Hz, it operates across a -20 to +60 °C ambient range and is rated for IP20 finger-safe touch protection on the front. Snap-on mounting onto a DIN rail. The 18.5 mm width and 68 mm depth leave room for adjacent devices in a crowded enclosure — no special spacing needed for this release alone. Insulation voltage rated at 690 V with pollution degree 3, so it's suited for industrial panels where conductive dust or humidity is present.","metaTitle":"Siemens 3RV1902-1AM1 SIRIUS undervoltage release, 208 V AC 6","metaDescription":"Siemens 3RV1902-1AM1 SIRIUS undervoltage release for motor circuit breakers S00-S3. 208 V AC, 60 Hz.
